You should do your best to write your scripts so that they do not requireregister_globals to be on; Using form variables as globals can easily leadto possible security problems, if the code is not very well thought of.

It's still not working! I changed it to "On" in all the php.ini files I could find, yet I still have to use the line in your code above...

I am correct in thinking that, the security problem that the file is talking about is that people could just put whatever they want into the url rather than just clicking a link? If so I write all my scripts with this in mind anyway.
